Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

Physicists have demonstrated that waves can bounce off boundaries in time, not just in space, producing signals that behave ...

A team of New York University researchers announced in early February 2026 that they had created “levitating” time crystals, tiny particles suspended by sound waves that appear to defy Newton’s third ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Time feels like the most basic feature of reality. Seconds tick, days pass ...
